山東MNS低壓抽屜柜是一種使用高壓配電上面的柜體，所以這樣的柜體在安裝的時候需要注意一些事項。

Shandong MNS low-voltage drawer cabinet is a cabinet that uses high-voltage distribution, so there are some precautions to be taken when installing such cabinets.

1.山東MNS低壓抽屜柜正常生產過程中的標高或者垂直上面是允許有偏差的，一般是由于測量定位或者地面不平造成的，這個時候需要及時進行修改。

During the normal production process of Shandong MNS low-voltage drawer cabinets, deviations in elevation or vertical orientation are allowed, which are generally caused by measurement positioning or uneven ground. At this time, timely modifications are needed.

2.MNS柜體配電箱的鐵架上面不正，在安裝的鐵架之前沒有進行調整好，或者安裝的固定位置偏移造成的。這一塊一定要固定好。

2. The iron frame of the MNS cabinet distribution box is not aligned, and it was not adjusted before installation, or the fixed position of the installation is offset. This piece must be securely fastened.

3.MNS柜體配電箱盤面電具以及儀表不牢固這些都是很重要的。

3. It is important that the electrical appliances and instruments on the MNS cabinet distribution box panel are not securely fastened.

4.MNS柜體接地導線截面上面不夠或者保護地線截面不夠的話，是會出故障的，這些情況一般是公用建筑工程或者民用住宅上面是一定不要使用的。

If the cross-section of the grounding wire of the MNS cabinet is not enough or the cross-section of the protective ground wire is not enough, it will cause a fault. These situations are generally not suitable for public building projects or residential buildings.

5.MNS柜體的盤后配線如果排列不整齊的話，需要按照支路綁扎，然后固定在盤內。

If the wiring behind the MNS cabinet is not arranged neatly, it needs to be tied according to the branch and then fixed inside the panel.

山東MNS低壓抽屜柜結構特點：

Structural characteristics of Shandong MNS low-voltage drawer cabinet:

1、MNS型低壓開關柜框架為組合式結構，基本骨架由C型鋼材組裝而成。柜架的全部結構件經過鍍鋅處理，通過自攻鎖緊螺釘或8。8級六角螺栓堅固連接成基本柜架，加上對應于方案變化的門，隔板，安裝支架以及母線功能單元等部件組裝成完整的開關柜。開關柜內部尺寸，零部件尺寸，隔室尺寸均按照模數化(E=25mm)變化;

1. The MNS type low-voltage switchgear frame is a modular structure, with the basic skeleton assembled from C-shaped steel. All structural components of the cabinet frame have been galvanized and secured with self tapping locking screws or 8. The basic cabinet frame is firmly connected with 8-level hexagonal bolts, and the complete switchgear is assembled with components such as doors, partitions, installation brackets, and busbar functional units corresponding to the scheme changes. The internal dimensions, component dimensions, and compartment dimensions of the switchgear are all changed according to modularization (E=25mm);

2、MNS型組合式低壓開關柜的每一個柜體分隔為三個室，即水平母線室(在柜后部)，抽屜小室(在柜前部)，電纜室(在柜下部或柜前右邊)。室與室之間用鋼板或高強度阻燃塑料功能板相互隔開，上下層抽屜之間有帶通風孔的金屬板隔離，以有效防止開關元件因故障引起的飛弧或母線與其它線路短路造成的事故;

2. Each cabinet of the MNS type combination low-voltage switchgear is divided into three compartments, namely the horizontal busbar compartment (at the back of the cabinet), the drawer compartment (at the front of the cabinet), and the cable compartment (at the bottom or right side of the cabinet). The rooms are separated from each other by steel plates or high-strength flame-retardant plastic functional boards, and there are metal plates with ventilation holes between the upper and lower drawers to effectively prevent accidents caused by arcing or short circuits between busbars and other circuits due to faults in switch components;

3、MNS型低壓開關柜的結構設計可滿足各種進出線方案要求:上進上出，上進下出，下進上出，下進下出;

3. The structural design of MNS type low-voltage switchgear can meet the requirements of various incoming and outgoing line schemes: upper inlet and upper outlet, upper inlet and lower outlet, lower inlet and upper outlet, lower inlet and lower outlet;

4、設計緊湊:以較小的空間容納較多的功能單元;

4. Compact design: accommodates more functional units in a smaller space;

5、結構件通用性強，組裝靈活，以E=25mm為模數，結構及抽出式單元可以任意組合，以滿足系統設計的需要;

5. The structural components have strong universality and flexible assembly. With E=25mm as the modulus, the structure and pull-out units can be combined arbitrarily to meet the needs of system design;

6、母線用高強度阻燃型，高絕緣強度的塑料功能板保護，具有抗故障電弧性能，使運行維修安全可靠;

6. The busbar is protected by high-strength flame-retardant and high insulation strength plastic functional boards, which have anti fault arc performance and ensure safe and reliable operation and maintenance;

7、各種大小抽屜的機械聯鎖機構符合標準規定，有連接，試驗，分離三個明顯的位置，安全可靠;

7. The mechanical interlocking mechanism of drawers of various sizes meets the standard requirements, with three obvious positions for connection, testing, and separation, ensuring safety and reliability;

8、采用標準模塊設計:分別可組成保護，操作，轉換，控制，調節，測定，指示等標準單元，可以根據要求任意組裝;

8. Adopting standard module design: It can form standard units for protection, operation, conversion, control, adjustment, measurement, indication, etc., and can be assembled according to requirements;

9、采用高強度阻燃型工程塑料，有效加強了防護安全性能;

9. The use of high-strength flame-retardant engineering plastics effectively enhances the protective and safety performance;

10、通用化，標準化程度高，裝配方便。具有可靠的質量保證;

10. Universalization, high degree of standardization, and easy assembly. Having reliable quality assurance;
